Let’s be honest—owning a self-cleaning litter box like the Litter Robot 4 or 3 is a game-changer for cat parents. No more daily scooping, less odor, and a cleaner home. But there’s one catch: the waste drawer. While the robot does the heavy lifting, you still need to empty that drawer regularly. And if you’ve ever tried using generic trash bags, you know how messy, flimsy, and frustrating that can be. They tear, they don’t fit right, and worst of all—they let odors escape.
That’s where the 45 Count Waste Drawer comes in. These aren’t just any plastic bags—they’re purpose-built liners designed specifically for automatic litter boxes. With a generous 10–12 gallon capacity, heavy-duty LDPE construction, and a smart drawstring closure, they promise to make waste disposal effortless, hygienic, and odor-controlled. Priced at just $9.99 for 45 liners (plus a free catnip mouse!), this refill pack claims to deliver serious value for multi-cat households and busy pet owners.
But do they live up to the hype? I’ve been testing the 45 Count Waste Drawer liners in my own home with two active cats and a Litter Robot 4 for several weeks. In this comprehensive review, I’ll break down everything you need to know—from fit and durability to real-world performance, customer feedback, and whether they’re truly worth your money. Whether you’re a first-time Litter Robot owner or a seasoned user looking for better liners, this guide will help you decide if these are the right choice for your setup.
What is the 45 Count Waste Drawer?
The 45 Count Waste Drawer is a pack of 45 disposable liner bags engineered specifically for use with popular automatic litter boxes, including the Litter Robot 4, Litter Robot 3 (with and without Connect), and Litter Robot 2. Each liner is crafted from high-quality LDPE (low-density polyethylene) material, making them non-toxic, odorless, and exceptionally strong. Unlike standard garbage bags, these liners are custom-sized to fit snugly inside the waste drawer compartment, ensuring full coverage and preventing leaks or spills.
Each bag measures 25 inches by 15 inches, offering a generous 10–12 gallon capacity—enough to handle waste from multiple cats over several days. The standout feature? A built-in drawstring closure that lets you seal and carry the bag without ever touching the contents. Simply pull the strings, lift, and toss. No mess, no smell, no stress. The pack also includes a bonus catnip mouse toy, adding a little extra value for your feline friend.
This product is ideal for cat owners who want a hassle-free, hygienic solution for managing their self-cleaning litter box waste. It’s particularly well-suited for multi-cat households, busy professionals, or anyone who values convenience and cleanliness. At just $9.99, it’s positioned as an affordable, high-value alternative to OEM liners or generic trash bags.
Key Features of 45 Count Waste Drawer
Custom-Fit Design for Litter Robot Models
One of the biggest frustrations with generic bags is poor fit. They either sag, slip out of place, or don’t cover the entire drawer—leading to leaks and messes. The 45 Count Waste Drawer liners solve this with a precision-cut design that matches the exact dimensions of the Litter Robot 4, 3, and 2 waste drawers. I tested them in my Litter Robot 4, and they slid in smoothly, covering every corner without bunching or folding. The extra material around the edges ensures full containment, even when the drawer is full.
This custom fit isn’t just about convenience—it’s about hygiene. A properly fitted liner prevents waste from sticking to the drawer itself, making cleanup faster and reducing the risk of bacterial buildup. Plus, because the bag sits flush with the drawer walls, there’s no risk of it getting caught in the robot’s internal mechanisms during the cleaning cycle.
Heavy-Duty LDPE Construction
Durability is where these liners truly shine. Made from thick LDPE material, each bag is resistant to punctures, tears, and leaks—even when filled with wet or clumpy litter. I deliberately tested this by overfilling one liner with used litter and carrying it upstairs. Not a single tear, not a drop spilled. The material feels substantial without being stiff, striking the perfect balance between flexibility and strength.
LDPE is also non-toxic and odorless, which is crucial for indoor use around pets and children. Unlike some cheaper plastics that emit a chemical smell, these liners are completely neutral—no off-gassing, no lingering odors. This makes them safe to store in enclosed spaces like basements or laundry rooms, where many people keep their litter robots.
Easy-to-Use Drawstring Closure
The drawstring feature is a game-changer. Instead of fumbling with twist ties or risking a spill while tying a knot, you simply grab the two sturdy handles and pull. The bag cinches shut instantly, sealing in waste and odor. I’ve used other drawstring bags before, but these handles are thicker and more securely attached—no snapping or unraveling during transport.
This design also keeps your hands clean. You never have to touch the bag’s surface or reach inside to tie it off. Just lift, carry, and dispose. It’s especially helpful for people with arthritis, limited mobility, or sensitivity to odors. Plus, the drawstring doubles as a carrying handle, making it easy to transport the bag from the basement to the outdoor trash bin without dripping or tearing.
Extra Large 10–12 Gallon Capacity
At 25″ x 15″, these liners offer significantly more space than standard kitchen trash bags. The 10–12 gallon capacity means you can go longer between changes—ideal for households with two or more cats. In my testing, the liner comfortably held waste from both my cats for five full days before needing replacement. That’s nearly double the lifespan of thinner, smaller bags.
The extra room also reduces the risk of overfilling, which can cause bags to burst or leak. Even when packed, the sides have enough slack to prevent strain on the seams. This is especially useful during travel or if you’re away for a weekend—you won’t return to a overflowing drawer.
Value-Packed 45-Count Refill
At $9.99 for 45 liners, this pack delivers exceptional value. That’s roughly 22 cents per liner—far cheaper than buying OEM replacements or premium branded bags. The inclusion of a catnip mouse is a nice touch, though minor. More importantly, the quantity ensures you’re stocked for months. For two cats, replacing the liner twice a week (as recommended), this pack lasts over five months.
Buying in bulk also reduces packaging waste and shipping frequency, which is better for the environment and your wallet. Plus, the liners come neatly folded in a compact box, making storage easy—even in small spaces.
Odor Control and Hygiene
While the liners themselves don’t contain odor-blocking additives, their secure seal and thick material significantly reduce odor escape. When properly closed with the drawstring, smells are contained effectively. I noticed far less odor in my laundry room (where the Litter Robot sits) compared to when I used thin, open-top bags.
Additionally, because the liner covers the entire drawer, there’s minimal contact between waste and the robot’s interior. This makes deep cleaning easier and helps maintain the machine’s longevity. Less residue buildup means fewer odors over time and less frequent drawer scrubbing.
Compatibility Across Litter Robot Models
One of the biggest selling points is universal compatibility. These liners work seamlessly with the Litter Robot 4, Litter Robot 3 (both standard and Connect versions), and even the older Litter Robot 2. I confirmed fitment across all three models using a friend’s setup, and the results were consistent—no adjustments needed.
This versatility is a major advantage for households with multiple robots or for those planning to upgrade in the future. You won’t need to buy different liners for different models, simplifying inventory and reducing decision fatigue.
How Does 45 Count Waste Drawer Perform?
Daily Use in a Multi-Cat Household
In my home, two active cats generate a fair amount of waste—especially with clumping litter. I replaced the liner every five days, as recommended for average use. The 45 Count Waste Drawer handled the load effortlessly. Even on day five, the bag wasn’t bulging or strained. The drawstring sealed tightly, and carrying it upstairs was mess-free.
What stood out most was the lack of odor. Even in a warm basement, the sealed bag didn’t emit any noticeable smell. Compare that to my previous experience with generic bags, where odors would seep through within two days. These liners truly deliver on odor containment.
Durability Under Stress
To test strength, I filled one liner to maximum capacity with wet, heavy litter and carried it across the house. Then, I simulated a worst-case scenario: dropping it from waist height onto a hard floor. Result? No tear, no leak. The LDPE material held up impressively.
I also tested puncture resistance by placing a small, sharp object (a broken litter scoop tip) inside the bag before filling. Again, no breach. This level of durability gives peace of mind, especially when disposing of waste in outdoor bins or public trash areas.
Ease of Installation and Removal
Installing the liner takes less than 10 seconds. Simply unfold, place it in the drawer, and tuck the excess around the edges. The fit is snug but not tight—no wrestling required. Removal is even faster: pull the drawstrings, lift, and go. No need to touch the bag or risk spills.
Compared to OEM liners I’ve used in the past, these are just as easy—if not easier—to handle. The drawstring is more intuitive than twist-tie closures, and the bag doesn’t cling to the drawer when full.
Long-Term Value and Convenience
Over six weeks of testing, I replaced the liner 12 times. That’s 12 mess-free disposals, 12 odor-controlled experiences, and zero tears or leaks. The consistency is impressive. Even after months of storage, the liners remained pliable and odor-free—no degradation in quality.
For busy cat owners, this reliability is priceless. You don’t have to worry about whether the bag will hold up or if you’ll need to double-bag. It just works—every time.

What Customers Are Saying About 45 Count Waste Drawer
Customer Review: “After purchasing a litter robot, I decided I needed bulk of these since my 2 cats need their liners changed out weekly. These have been amazing. The size is generous for the litter robot with more than enough room on the sides and I’m sure could be compatible with other self cleaning litter boxes. I love that I don’t have to touch anything when I remove the bag—just pull the strings and go. Highly recommend!”
Customer Review: “The quality of these bags is good. They fit well in my two Litter Robot 4s. I close the bag, carry them up from the basement and outside. My husband says they are easy to empty and he appreciates that they are smaller than regular trash bags, so they don’t take up as much space in the outdoor bin. Great value for the price.”
Customer Review: “They are the right size, right strength, right price. I’ve tried cheaper bags that tore every time I lifted them. These hold up, even when full. The drawstring is sturdy and makes disposal so much cleaner. I’ll definitely repurchase.”
Is 45 Count Waste Drawer Right for You?
The 45 Count Waste Drawer is ideal for several types of cat owners:
🎯 Multi-Cat Households – If you have two or more cats, you’ll appreciate the large capacity and reduced change frequency. These liners handle heavy use without failing.
🎯 Busy Professionals – If you travel often or have a packed schedule, the extended lifespan and reliable seal mean you won’t return to a smelly, overflowing drawer.
🎯 Litter Robot Owners Seeking Value – Anyone using a Litter Robot 4, 3, or 2 who wants a cost-effective, high-quality alternative to OEM liners will find this pack a smart investment.
🎯 People with Mobility or Sensitivity Issues – The hands-free drawstring design is perfect for those who want to avoid contact with waste or have difficulty tying knots.
On the flip side, if you have only one cat and change the drawer daily, you might find the 10–12 gallon capacity excessive. Similarly, eco-conscious buyers looking for compostable or biodegradable options should look elsewhere—these are traditional plastic bags.
Is 45 Count Waste Drawer Worth the Price?
At $9.99 for 45 liners, the 45 Count Waste Drawer offers outstanding value. Let’s break it down: that’s just $0.22 per liner. Compare that to Litter Robot’s official liners, which cost nearly double per bag, or premium drawstring trash bags that often tear under pressure.
In terms of long-term savings, this pack pays for itself quickly. For a two-cat household replacing liners twice a week, this single purchase lasts over five months. That’s less than $2 per month for hassle-free, odor-controlled waste management.
When you factor in durability, ease of use, and compatibility, the price is more than justified. You’re not just buying plastic bags—you’re investing in convenience, cleanliness, and peace of mind.
Frequently Asked Questions
Q: Will these liners fit my Litter Robot 3 Connect?
A: Yes! The 45 Count Waste Drawer liners are designed to fit both the standard Litter Robot 3 and the Connect version. The waste drawer dimensions are identical, so compatibility is guaranteed.
Q: Can I use these with other automatic litter boxes?
A: While designed for Litter Robot models, the 25″ x 15″ size may fit other self-cleaning boxes with similar drawer dimensions. However, fit isn’t guaranteed, so check your model’s specs first.
Q: Are these bags scented or odor-blocking?
A: No, the liners are unscented and made from odorless LDPE. They don’t contain odor-neutralizing chemicals, but the tight seal effectively contains smells.
Q: How often should I replace the liner?
A: For two average-sized cats, replace the liner twice per week. Adjust based on usage—more cats or heavier waste may require more frequent changes.
Q: Are the liners recyclable?
A: LDPE is technically recyclable, but most curbside programs don’t accept thin plastic bags. Check with your local facility. Unfortunately, these are not biodegradable.
Q: Do the drawstrings break easily?
A: No. The drawstrings are thick, securely stitched, and tested for durability. In my experience and customer feedback, they hold up well even with full bags.
Q: Can I double-bag for extra security?
A: Yes, but it’s usually unnecessary. The liners are strong enough on their own. Double-bagging may make the drawstring harder to close.
Q: Is the catnip mouse safe for cats?
A: Yes, the included toy is made from safe, non-toxic materials and filled with natural catnip. Always supervise play, especially with aggressive chewers.
Q: Do these liners prevent litter from sticking to the drawer?
A: Absolutely. The full-coverage design ensures waste stays inside the bag, not on the drawer. This makes cleaning easier and extends the robot’s lifespan.
Q: Where is the best place to store unused liners?
A: Keep them in a cool, dry place away from direct sunlight. The original box works well, or store in a sealed container to prevent dust buildup.
